DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. Also, the following detailed description does not limit the invention.

The term “content” as used herein, is intended to be broadly interpreted to include, for example, visual data or visual data and audio data, such as media content and user interfaces (UIs). By way of example, content may include television programming (e.g., local programming, national programming, free programming, live-programming (e.g., a live broadcast, etc.), etc.), movies, sports, news, video-on-demand content, premium channel content, television guides, weather information, sports information, traffic information, horoscope information, games, Internet content, etc. The content may be in various formats, such as, for example, standard definition, high-definition, 3-D, etc.

TSPs have limited resources for delivering content to their customers. For example, content delivery architectures may reach its capacity due to the number of channels, etc. Under such circumstances, for example, the addition of new channels or the offering of high-definition channels may cause channel capacity to become depleted. TSPs may use Internet Protocol Television (IP TV) to supplement their delivery of content to their customers.

According to exemplary embodiments described herein, a television content distribution network (TCDN) may include the use of IP channels to deliver content (e.g., IP TV, etc.). According to the exemplary embodiments, the TCDN may include network devices that provide the content to customer devices based on bandwidth-efficient measures. According to an exemplary embodiment, when the network devices receive a request for an IP channel, the network devices may determine whether the request may be satisfied by a customer device that is already receiving the IP channel. If the network devices determine that the other customer device may provide the IP channel to the customer device that is making the request, the requesting customer device may receive the IP channel from the other customer device. In this way, the bandwidth between the network devices and customer devices may be efficiently used, etc.

According to an exemplary embodiment, the network devices may provide the requesting customer device a network address of the customer device already receiving the requested content. According to an exemplary embodiment, the network devices may provide the requesting customer device the network address of the customer device and a network address of a secondary customer device. The secondary customer device may be considered a backup device in case the customer device is unable to provide the requested content to the requesting customer device due to device or network failures, etc. According to an exemplary embodiment, in the event that a secondary customer device may not be available, the network devices may act as the backup device.

FIGS. 1B-1H are diagrams illustrating an exemplary process for providing content based on bandwidth-efficient measures according to an exemplary embodiment. While particular messages or information may be illustrated as being sent by or received by a particular device in environment 100, according to other embodiments, the exemplary messages may be sent by or received by a different device or a combination of devices. Additionally, or alternatively, while examples described may refer to a particular protocol, according to other embodiments, other protocols may be used, in addition to, or instead of, that described.

Referring to FIG. 1B, according to an exemplary process, network device 110-1 may be providing content to a customer (not illustrated) that is watching TV 130-N. According to an exemplary embodiment, the content may be delivered to TV 130-N using an IP channel.

In FIG. 1C, another customer (not illustrated) may request the same content. For example a content request may be sent by the other customer via TCDN interface 135-1 to network device 110-1. Network device 110-1 may receive the content request. Referring to FIG. 1D, network device 110-1 may determine whether the content is already being delivered to another CPE. By way of example, network device 110-1 may determine whether another TCDN interface device 135 is receiving the requested content. In this example, network device 110-1 may determine, among other CPEs, that TCDN interface 135-N is receiving the content requested.

As illustrated in FIG. 1E, network device 110-1 may select one or more TCDN interface devices 135 based on performance metrics, such as, for example, hop count, latency, etc., (e.g., between TCDN interface device 135-1 and other TCDN interface devices 135, etc.), network topology information, network state information, network cost information, bandwidth utilization, and/or network optimization parameters. According to an exemplary embodiment, network device 110-1 may select a primary TCDN interface device 135 to deliver the requested content to the requesting TCDN interface device 135-1. According to another exemplary embodiment, network device 110-1 may select a primary TCDN interface device 135 and a secondary TCDN interface device 135. According to an exemplary embodiment, in the event a primary TCDN interface device 135 is not available, network device 110-1 may provide the content to TCDN interface device 135-1. According to an exemplary embodiment, in the event a secondary TCDN interface device 135 is not available, network device 110-1 may act as the secondary/backup device. According to an exemplary embodiment, in the event that a primary TCDN interface device 135 and a secondary TCDN interface device 135 are selected and the primary TCDN interface device 135 fails, the secondary TCDN interface device 135 may take over as the primary TCDN interface device 135. Further, network device 110-1 may select another secondary TCDN interface device 135.

In this example, it may be assumed that network device 110-1 is able to select a primary TCDN interface device 135 and secondary TCDN interface device 135. According to an exemplary embodiment, as illustrated in FIG. 1F, network device 110-1 may send the network addresses of the primary and the secondary TCDN interface devices 135 to TCDN interface device 135-1. For example, with reference to FIG. 1G, TCDN interface devices 135-4 and 135-N may be receiving the requested content (e.g., from network device 110-1, from another TCDN interface device 135, etc.). In this example, TCDN interface device 135-N may correspond to the primary TCDN interface device 135 and TCDN interface device 135-4 may correspond to the secondary TCDN interface device 135.

According to an exemplary embodiment, TCDN interface device 135-1 may make a content request to TCDN interface device 135-N based on the network address received. TCDN interface device 135-1 may send a content request to TCDN interface device 135-4 when TCDN interface device 135-1 is no longer receiving the requested content from TCDN interface device 135-N (e.g., due to device failure, network failure, etc.). For example, TCDN interface device 135-1 may send the content request after a timeout procedure.

As illustrated in FIG. 1H, TCDN interface device 135-N may provide the requested content to TCDN interface device 135-1. In this way, among other things, the bandwidth between network devices 110 and customer devices may be efficiently used, etc.

According to other embodiments, TCDN interface device 135-N and/or TCDN interface device 135-4 may receive the network address of TCDN interface device 135-1. For example, network device 110-1 may provide the network address to these devices. According to such embodiments, TCDN interface device 135-N may initiate communication with TCDN interface 135-1 to provide the requested content to TCDN interface device 135-1.

As previously described, according to exemplary embodiments, network devices may provide content to customer devices based on bandwidth-efficient measures. A further description of bandwidth-efficient processes is described with reference to FIGS. 3A-3E.

According to an exemplary embodiment, network device 110 may provide content to customer premises 125 (e.g., customer premises 125-1 through 125-N). According to other embodiments, customer premises 125 may be provided content from another customer premises 125 or within the same customer premises 125 (e.g., within a household having multiple TCDN interface devices, etc.).

As illustrated in FIG. 3A, customer premises 125-N may be receiving content. Customer premises 125-1 may send a content request to network device 110-1. According to an exemplary embodiment, when network device 110-1 receives the content request, network device 110-1 may determine whether to use bandwidth-efficient measures. By way of example, network device 110-1 may consider available bandwidth (e.g., is the available bandwidth higher or lower than a threshold value, etc.), as well as one or more of the following factors, such as, load balancing/network optimization parameters (e.g., associated with network device 110-1 delivering the content or another CPE), network topology/network state information (e.g., are there available CPEs, hop count, latency, quality of service (QoS), failures, outages, are available CPEs receiving content from network device 110 or another CPE, etc.), network cost, etc.

As illustrated in FIG. 3B, when network device 110-1 determines that bandwidth-efficient measures may be taken, network device 110-1 may determine whether the requested content is already being delivered to another customer premises 125 or within the same customer premises 135. For example, network device 110-1 may manage a database that maps content with network addresses. Alternatively, another device (not illustrated) may provide this information to network device 110-1. Network device 110-1 may also determine whether the customer premises 125 (e.g., customer premises 125-N) is receiving the content from network device 110-1, from another customer premises 125, etc. For example, there may be equipment limitations associated with the CPEs, QoS issues, etc., related to daisy-chaining CPEs for the delivery of the requested content.

Additionally, referring to FIG. 3C, network device 110-1 may select appropriate customer device(s). For example, according to an exemplary embodiment, network device 110-1 may consider load balancing/network optimization parameters, network topology/network state information, etc. As previously described, according to an exemplary embodiment, network device 110-1 may select a primary and a secondary CPE. In the event that a secondary CPE is not available, network device 110-1 may act as a backup device. As illustrated in FIG. 3D, according to an exemplary embodiment, network device 110-1 may provide the network addresses of the primary CPE and the secondary CPE to customer premises 125-1. In this example, the primary CPE may be associated with customer premises 125-N and the secondary CPE may correspond to network device 110-1, as illustrated in FIG. 3E. In the event that the primary CPE is unable to provide the requested content, network device 110-1 may provide the content. Alternatively, network device 110-1 may determine whether another secondary CPE is available.

Described below are exemplary processes associated with the bandwidth-efficient delivery of content.

FIGS. 4A and 4B are flow diagrams illustrating an exemplary process 400 for providing bandwidth-efficient delivery of content.

Television content may be provided to customers (block 405). For example, as previously described, network device 110 may deliver content to customers. According to an exemplary embodiment, the content may correspond to IP channel content. In some instances, the content may also be delivered by other CPEs.

A content request may be received (block 410). For example, as previously described, network device 110 may receive a request for content.

It may be determined whether to use bandwidth-efficient measures (block 415). For example, as previously described, network device 110 may determine whether bandwidth-efficient measures may be used to deliver the requested content. Network device 110 may consider various factors, such as, for example, available bandwidth, network topology, network state, etc.

If it is determined that bandwidth-efficient measures may not be used (block 415-NO), then network device 110 may deliver the requested content to the requesting CPE. If it is determined that bandwidth-efficient measures may be used (block 415-YES), then network device 110 may determine whether the requested content is already being delivered to another CPE, as illustrated in FIG. 4B. For example, network device 110 may determine whether network device 110 is already delivering the requested content to another CPE or another CPE is receiving the requested content from yet another CPE.

If it is determined that the content is not already being delivered (block 425-NO), then network device 110 may deliver the requested content to the requesting CPE. Alternatively, in the event that bandwidth utilization does not permit network device 110 to deliver the content, the content may not be delivered or the delivery of the content may be delayed.

If it is determined that the content is already being delivered (block 425-YES), then network device 110 may select a primary CPE and a secondary CPE to deliver requested content. For example, as previously described, according to an exemplary embodiment, network device 110 may select primary and secondary CPEs based on various factors, such as, for example, network topology, network state, etc. According to other embodiments, network device 110 may not select a secondary CPE. Additionally, according to an exemplary embodiment, network device 110 may select itself to act as a backup device (i.e., a secondary content delivery device).

Network addresses associated with the primary and the secondary CPEs may be provided (block 440). For example, as previously described, according to an exemplary embodiment, network device 110 may provide the requesting CPE with the network addresses of the primary and the secondary CPEs. According to other exemplary embodiments, network device 110 may provide the network address of the requesting CPE to the primary and/or the secondary CPEs.

Although FIGS. 4A and 4B illustrate an exemplary process 400 for providing bandwidth-efficient delivery of content, according to other embodiments, process 400 may include additional operations, fewer operations, and/or different operations than those illustrated in FIGS. 4A and 4B and described. Additionally, while process 400 is described with reference to exemplary devices (e.g., CPE (e.g., TCDN interface device 135, etc.), network device 110, etc.) described in process 400 may be performed by a device or combination of devices other than those specifically mentioned.
